Should the dictionary be adding more female-authored sources (or bolstering existing ones) as a matter of principle?

But if women were, at various periods, contributing only a small percentage to the total of written sources, would that be an unwarrantable distortion?

Bibliographical studies since 1988 have confirmed 'the steady emergence of women writers early in the eighteenth century, followed by their explosive increase in its final three decades' - so that in 2000 Raven and Forster were able to show that women produced at least a third of the novels published in the late eighteenth century. (See Stanton 1988: 253; Raven, Garside, et al. 2000: vol. 1, pp. 46-7, Table 6, and accompanying discussion).

What are the issues here and how does one assess them and decide on lexicographical policy?

Here it can be seen that OED3 has increased quotations from Eliot, Burney, and especially Austen. Martineau and Braddon are down, however. What will have influenced the lexicographers' decisions in these cases? (Looking at individual quotations is probably the place to start but is laborious and time-consuming.) Are there other female-authored sources which OED3 have introduced into the dictionary?
